beta-ray-generator

German Architect Andre Broessel believes he has a solution that can “squeeze more juice out of the sun”, even during the night hours and in low-light regions. His company Rawlemon has created a spherical sun power generator prototype called the beta.ray. His technology will combine spherical geometry principles with a dual axis tracking system, allowing […]

Solar Energy News -- ScienceDaily

Solar Energy Information. Read the latest news and techniques for efficient solar photovoltaic power, new solar energy systems and more.

Materials scientists find inorganic compounds quench defects in perovskite-based solar cells and expand their tolerance of light, humidity and heat.

Researchers have developed a way to map strain in lead halide perovskite solar cells without harming them. Their approach can image the grain structure of a perovskite solar cell, showing that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell. Crystal misorientation creates small-scale defects in the grain structure, which interrupt the transport of electrons within the solar cell and lead to heat loss.

A new study shows that to achieve the biggest improvements in public health and the greatest benefits from renewable energy, wind turbines should be installed in the Upper Midwest and solar power should be installed in the Great Lakes and Mid-Atlantic regions.

Engineers, along with an economist, have created an energy model that helps to remove carbon-generated power from the US electric grid -- replacing it with a greener, financially feasible wind, solar and hydro energy system.

Next-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term 'green technology.' Adding the protein bacteriorhodopsin (bR) to perovskite solar cells boosted the efficiency of the devices in a series of laboratory tests, according to an international team of researchers.

The transition from coal to natural gas in the US electricity sector is reducing the industry's water use, research finds. For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260 gallons. Switching to solar or wind power could boost these savings even more.

Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction.

A team of researchers performed wind tunnel experiments to determine the role of asymmetry caused by the orientation of a volleyball on its aerodynamic characteristics. They found that switching from the standard panel arrangement to a hexagonal or dimpled pattern may improve the consistency of flight, with many potential applications in aviation.

The wind is always blowing somewhere, but deciding where to locate a wind farm is a bit more complicated than holding up a wet finger. Now a team of researchers has a model that can locate the best place for the wind farm and even help with 24-hour predictions of energy output.

An increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation's electricity. Scenarios developed by various groups, including U.S. Department of Energy, indicate that a four- to five-fold expansion over current levels of electricity produced by wind is needed by the year 2050 to help meet U.S. carbon emission reduction goals.

Europe has the capacity to produce more than 100 times the amount of energy it currently produces through onshore windfarms, new analysis has revealed.

Advances in adapting the technology and better methods for predicting wind conditions have fanned significant growth of the use of wind turbines for electricity in the last 40 years. A new report takes stock of where the field is now and what lies ahead. Researchers surveyed the growth of wind technology as a source of renewable energy and assessed its viability for continuing to capture larger shares of the electricity market.
